Were testing UltraVNC on our network and loving it so far. We got the MS Logon to work fine with our domain however when we try to connect to one of the PCâ€™s on the same domain its asking us for our network username and passwd. Once we put in that information we able to connect to the PC fine, however is a way for the credentials to be pass on so our support staff doesnâ€™t have to enter there username and password all the time.
